ive some data about the world's light pollution.
I want to show them in a background(world landmap) and animate the raster data year to year.
I am suffering for 2 days, any ideas?

I have spent hours trying to figure this out. Watched videos that show how to round (using Bevel) the edges or edge of a uniform mesh cube. Works great.
But my mesh cube is rectangular 10x1x0.2 shape. And I can't get it to work. The edge seems to be beveled proportionally based on the size of the adjoining faces. I want non-proportional beveling. I know this is probably something easy I am missing, but I have spent hours and can't find the answer. I just want to evenly round this edge when looking at the cube.

Please help me out for drawing grouped bar chart in dimple js.
I have to draw the graph where x-axis is timeAxis and y-axis is measureAxis.
I have seen many code snippets when they have done this. But, i am unable to do this with x-axis as timeAxis.
Any help would be appreciated.
I'm afraid the time axis doesn't support grouping. If you want to use dimple the only way is to use a category axis (which does work with time dimensions, but will evenly space and size each time value regardless of real interval).
Goal
I want to display data into a chart control. Like so:
Current Problem
My issue is the data (blue line) goes out of the chart. As seen above, it seems as if my data exceeds the viewing pane... I'd like to be able to view the whole thing.
Is it possible to create some sort of padding? Keep in mind, not all values will be in percentage...
The solution I used is multiplying the YAxis maximum by 5%.
This creates a small padding over my maximum values which enables me to view it correctly. Not very elegant but it does the job for now.
Perhaps there are better answers but this worked great.
I am working on a corporate-level summary report for my employer. Because this is a fairly high-level report, I'm trying to "pretty" it up a bit (I think the standard SAS output is exceptionally ugly). I've managed to include graphics using ODS REGION and the like, but I'm having trouble generating a fairly basic bar chart.
All I want to do is draw boxes onto the PDF file by specifiying X,Y and W,H and the background color. I've gotten close using this SUGI paper (which employs ODS REGION with a PROC GSLIDE).
That works OK, but I've run into many vexing little issues. For example:
There's a minimum height and width for GSLIDE (appx 3 points) which has made it very difficult to represent small numbers on my bar graph
The corners of GSLIDE are slightly rounded, causing strange looking "artifacts" when attempting to overlay and stack them
There's apparently a "maximum" width (appx 480 points). I think I might be able to solve this with the GOPTIONS VSIZE attribute, but I have to be careful because if the ODS REGION and GSLIDE are exactly the same size, then SAS (for some reason) thinks that the GSLIDE is bigger than the REGION and fails to render GSLIDE properly.
I've searched the internet for an easier approach, but it seems there are few SAS programmers trying to do what I'm doing. I know that I'm reinventing the wheel a bit in that SAS providers bar charts via SAS/GRAPH, but they don't provide the level of customization I need to display the results the way I want them.
How can I draw a simple rectangular shape, with nice square corners, and no weird width/height limitations, on a PDF file?
This isn't direclty relevant to the question, but since it's been brought up, here's an idea of what the bar chart looks like:
Each row measures a metric across a mutually exclusive sub-section of a larger population. The Gray bar represents the total size of the population being measured. The blue bar measures the metric (and the reported number is the metric across the sub-section). The "white bar" is the size of the total population. (The light blue bar is an alternate metric displayed only for those who are curious - it will always be smaller than the blue bar.) Some sub-sections contain no data, so they are displayed as "N/A".
There's also a rolling total. So, after one or a few sub-sections are reported, they are rolled into the rolling total. The gray background groups the related sub-sections, with the rolling total reported at the bottom.
This is pretty much exactly what I want this chart to look like. If it can be done using standard SAS charts, I'd be happy to use them - but I think it's been easier to get this effect on my own by painting the graph myself.
I found a partial answer... you can use a LayoutRegion defined via PROC TEMPLATE to set the background color of an ODS REGION. You still must "put something" within the region to force SAS to render it (for example, ODS TEXT = " ";), but it removes at least one pain point: minimum and maximum sizes.
Unfortunately, the corners are still rounded, but I'll update this answer if I can figure out a way to fix that via an attribute or something.
I have a layer with a sprite of a simple black donut. I want the user to be able to draw on the sprite in a different color (which I've managed to do without any problem using CCRenderTexture).
My question is how I can calculate whether the image has been traced at least 95% (meaning, find out when 95% of the black pixels are now the new color). I've tried methods like taking a screenshot of the layer and counting the number of black pixels, but it hasn't worked that well (using this solution: https://stackoverflow.com/a/1262893/1577738).
It would be even better if I could just change the color of each pixel as it's touched (to avoid issues with coloring out of the lines). I could theoretically just split the donut into like 10 sprites and change that section's color if the user touches it, but that seems ridiculous if I give the user options to use a bunch of different colors.
Am I going about this the wrong way? Your suggestions are much appreciated!
Reading pixel colors will be rather inaccurate and slow. I suggest dividing the area into smaller rectangles (ie 8x8 or 4x4) and then flag each as "visited" when the user draws on it. If most rectangle areas are flagged, the user has drawn on most parts of the texture.
